A researcher at the service’s Weapons and Materials Directorate lays out a vision for additive printers on the battlefield.

 

If you go by the Hype Cycle — Gartner’s annual tech-buzz assessment — then consumer 3D printing is about to tumble from the “peak of inflated expectations” into the “trough of disillusionment,” part of the coming five- to 10-year slog to the practical applications that await atop the “plateau of productivity.” But Larry “L.J.” Holmes, the principal investigator for materials and technology development in additive manufacturing at the U.S. Army Research Laboratory, (ARL) isn’t waiting around for that.

In a presentation last month at the Intelligence and National Security Alliance summit, Holmes sketched out a variety of potential uses for 3D printing for the military, ranging from intelligence to communications to terraforming the battlefield. Here are a few highlights.

D3O Lab has received funding from the US Army's Program Executive Office (PEO) Soldier for the evaluation of prototype shock-absorbing helmet system solutions.

 

Under the one-year foreign comparative testing (FCT) programme, the company will assess the blunt trauma characteristics of its prototype D3O trauma reduction and unrivalled shock technology (TRUST) helmet system.

 

Specifically, the PEO Soldier programme office for protection and individual equipment (SPIE) aims to assess the impact performance of the D3O shock-absorbing helmet system when it is fitted into combat helmets and impacted at 14ft/s, according to military standards.

"D3O TRUST has been developed to improve impact protection against blunt force trauma."

 

Originally developed with funding support from the Technology Strategy Board, D3O TRUST has been developed to improve impact protection against blunt force trauma, a physical trauma caused by a collision with a non-penetrating object or surface.

 

The helmet uses the company's unique patented technology to offer superior impact protection and comfort compared with existing helmets.

 

D3O general manager Mostyn Thomas said: "D3O has conveyed to this product the R&D expertise it has honed in creating industry-leading protective helmets for the US team sports market, particularly American football and baseball.

 

"D3O is committed to creating personal protection equipment, which will help to reduce the thousands of very common injuries affecting soldiers each year."

 

The D3O TRUST helmet consists of three individual parts, including a shock-absorbing liner to absorb and dissipate the energy released in the collision, an inflatable system that fits the solution to a range of head shapes, and a skull cap to offer more comfort and help with sweat management.

 

The shock-absorption liner is in turn encapsulated using D3O's new smart skin technology, which is a wipe-clean thermoplastic polyurethane that provides durability and an anti-microbial barrier.

 

Blunt force trauma is the principal cause of traumatic brain injuries (TBI) and mild TBI, with the former affecting nearly 31,000 UK soldiers in Afghanistan and Iraq between 2006 and 2013.

PHOENIX | The U.S. Army has ordered thousands of additional helmet sensors that can be used to record the severity of head movements and impacts during a combat-related blast or explosion. The sensors, called Headborne Energy Analysis and Diagnostic Systems (HEADS), are provided by BAE Systems and are revolutionizing the way data is captured, stored and retrieved to determine the effects that improvised explosive devices and other blunt impacts have on a Soldier’s head.

 

Under a new $16.9 million contract, BAE Systems will deliver the HEADS Generation II sensors by January of next year. This order will be in addition to approximately 20,000 sensors that are already in use.

 

“Traumatic Brain Injuries are known as a signature injury for Soldiers in Iraq and Afghanistan,” said Don Dutton, vice president and general manager of Protection Systems at BAE Systems. “The Army has an urgent demand for technologies that help identify individuals who may be in need of medical assistance for potential head and brain injuries. The data collected by HEADS during a traumatic event can be used to develop better protective equipment and for supporting further medical treatment.”

 

Positioned beneath the crown suspension pad of most combat helmets, HEADS allows the Army and medical practitioners to continuously measure and collect critical and potentially lifesaving data. These include impact duration, blast pressures, ambient temperature, angular and linear accelerations, as well as the exact times of single or multiple blast events. The placement of the sensor inside the helmet ensures that accurate measurements are achieved.

 

From late 2007 and into 2008, BAE Systems delivered more than 7,600 HEADS Generation I sensors to the U.S. Army and Marine Corps. Then HEADS Generation II was developed, introducing a wireless technology to download summary data of recorded events. Other enhancements to the sensor included a longer battery life, expanded pressure measurement and angular rate data.

 

The latest $16.9 million award is part of a five-year contract awarded in June 2010. This award brings the cumulative value of the contract to approximately $34 million.

 

BAE Systems is a leading provider of Soldier protective and load carrying equipment in the United States, producing a significant portion of the nation’s body armor, tactical vests, combat helmets and load carrying systems. Not only is the company focused on the design, development and production of leading edge survivability products, but its integration of advanced materials into manufacturing, rigorous product testing and field trials support the company’s focus on the men and women who serve in the armed forces.

Better Combat Helmets for Soldiers in Afghanistan

 

 

Nov 21, 2011 ASDNews Source : MoD Australia

Minister for Defence Materiel Jason Clare today announced upgrades worth a million dollars to combat helmets worn by soldiers in Afghanistan.

The upgrade to 2,000 helmets was completed last month.

It includes fitting new padding and harnesses inside the helmet to increase comfort and functionality.

Another 1,500 combat helmets will be fitted with the new padding and harnesses in the first quarter of next year for soldiers deploying to Afghanistan in the future.

Further upgrades to better integrate night vision equipment and to enhance blunt impact protection to the current combat helmet will also be undertaken by the Diggerworks Team next year.

Mr Clare said this was an issue soldiers had raised with him this year.

"I met with soldiers from Mentoring Taskforce 3 earlier this year before they deployed to Afghanistan and they told me this was something they wanted fixed. Diggerworks have done a great job in rolling this out so quickly," Mr Clare said.

"The new padding and harness make the helmet more comfortable and easier to wear."

Diggerworks is a specialist team of combat experienced soldiers, scientists and engineers established to develop and deliver new equipment to better protect Australian troops.
